provide improved joints between the various members of the chassisframe; and to provide an improved arrangement of channel members forforming channel columns intermediate the end portions of the sidemembers of a chassis frame where rigid support is required.

An illustrative embodiment of my invention is shown in the accompanyingdrawing, in which:

Fig. 1 is a plan view of a chassis frame embodying my invention.

Fig. 2 is a side elevation of the frame shown in Fig. 1.

Fig. 3 is a transverse section taken on line 3-3 of Fig. 1.

Fig. 4 is a fragmentary perspective view showing the end of a crossmember of a frame in detail.

In the form shown, the chassis frame comprises spaced longitudinal sidemembers 1 and 2, each comprising a pair of channel bars 3 and 4:, andtransverse channel members 5. The channel bar 4 is seated between thesides 6 of the channel bar 3 at the intermediate portions of the chassisframe and the sides of the two bars are riveted together. The bar 3extends rearwardly beyond the extremity 7 of the bar 1 which protrudesin advance of the extremity 8 of the bar 3. This construction provideschannel columns in the side members at their intermediate portions whererigidity is desired, and single channel bars at the front and rearportions of the side members for absorbing the shock and vibration whichis received from the front and rear wheels respectively, over whichthese parts of the frame are located.

The webs 10 of the transverse bars 5 have flanges 9 on theirrespectively opposite ends which extend into the channel-ways of theinner channel bars land abut the websll of the same. These flanges aresecured to the webs 11 by rivets 12. Mounted on the upper and lowersides of the frame are gusset plates 13 and 14 respectively which aresecured by rivets, or other suitable means, to the sides 15 of thechannel members 5, and to the sides 6 of the channel bar 3.

Mounted on the outer edges of the side members 1 and 2, in alignmentwith the members 5, are channel-shaped Outriggers 16 which have a flange17 adjacent the exterior surface of the web of the channel bar 3 towhich they are secured by rivets 18. The rivets 18 are staggeredrelative to the rivets 12 and the adjacent web and flange 11 and 9respectively are provided with registering apertures 19 through whichthe heads of the rivets 18 may be held by a suitable tool while theiropposite ends are peened over. The sides of theoutriggers 16 are alsorigidly secured to the sides 6 of the channel bar 3 by rivets 20.

In the above construction, the sides of the chassis frame are reinforcedat their intermediate portions without excessively increasing the weightof the structure.

Although but one specific embodiment of this invention has herein beenshown and described, it will be understood that various changesincluding the size, shape and arrangement of parts, may be made withoutdeparting from the spirit of my invention and it is not my intention tolimit its scope other than by the terms of the appended claims.

I claim:

1. In a chassis frame, side members each including a pair of overlappedchannel bars, one seated between the respectively opposite side flangesof the other, the webs of said channel bars being spaced apart so as toform a tubular structure in the intermediate part of each side member,and cross members connecting said side members, and outriggers mountedon the outermost channel bars of said side members comprisingchannelshaped members each having an inwardly disposed web extensionsecured to the web of said outermost channel bars and over-' hangingside flanges secured to the side flanges of the latter channel bars.

2. In a chassis frame, a side member in- V eluding a channel bar havinga vertical Web and a pair of inwardly extending horizontal flanges, anoutrigger on said channel bar comprising a channel shaped arm having apair of horizontal flanges and a vertical Web,

the joining portions of the flanges and Web of said arm being severed atthe inner end portion thereof, and a flange formed'on the inner endportion of the Web of said arm extending substantially parallel to theWeb of said side member and secured thereto, said 15 side member beingreceived between and secured to the'severed portions of the flanges ofsaid arm.
